BOILER-COMPOUllD-FEEDNG SYSTEM.

Application filed December 22, 1924. Serial No. 757,472.

rl`his invention relates to new and usetul improvements in boiler-compound feeding systems.

lhis invention has to do with systems of the character described in which compounds for removing incrustation, preventing rust and the like may be injected into the leed water of tlieboiler.

rih-e object ot' the invention is to provide a' system whereby corrosion, incrustation and foaming may be reducedto al minimum.

A particular object is to provide a system whereby the said cmu-pounds may be conveyed from a storage container? to the condenser', pump, trap, heater, etc., as well as to the boiler, thus keeping all parts of the steam generatingplant in a highly etlicient state.

Another objectI is to provide a system whereby the conipound may be segregated and directed to any particular element ot the plant, such as a heater, a trap, the boiler or the like.

A further =object is'tol provide a system which is seit-cleaning, whereby the coinpound may be circulated as desired through any particular part or parts.

A. still further object is to provide a systei'n whereby exhaust losses are eliminated.

Another object' is'the provision of a system involving` a simple construction and arrangen'ient ot pipes and valves at a low cost, thus making installations comparatively easy and readily available under varying conditions.

A construction designed to carry out the invention will be hereinafter described together with other' Yleifitures' ot" the invention.

The invention will be more readily understood from a reading of the Jfollowing speciiication and by reference to the accompanying drawiugs'` in which an example oit the invention is shown, and wher`ein:-

Fig. l isa diagramin'atical view ot the sys teni and l Fig. 2 is asimilar vievot the distributing end ot the system.'

ln the drawings the numeral l() desig-v nates a storage tank and 1l an auxiliary storage tank adjacent thereto.` A siphon pipe l2 extending in the tank l() is connected with a pipe 13 entering the lower end oi' the tank l1. A vglobe valve 14k' in the pipe 13 controls the passage of liquidffrom'the tank l() yto the tank 1l. An injector l5 of the construction is mounted above the tank l0. A

steam line i6 including a valve 17 is connected to the upper end of the injector. An exhaust pipe 'i8 leads from the injector and discharges into the tank 10.

A suction pipe 19 has a screen 2O on its bottom near the bottoni of the tank and includes a check yvalve 2l just above the screen, seating against a back pres-sure. The suction pipe extends upwardly including, resp ictively, a valve Q2, connections 23 and QA, `valve 25 and "E" 26. A branch suction pipe 27 leads from the" connection 23 over and down into the tank l1 andV has ascreen 28 and check valve 29 on its lower end. The suction pipe 27 includes a globe valveBO aid jacent the connection 23. From the connection QA a suction pipe 3l extends to the upper portion oi" the injector.

A pipev 39. Vextends down from the water column' 33 of the boiler. This is a blow-oli pipe and includes, respectively, a globe valve 3l, connections 35, 36 and 3T and a globe valve 38. A discharge pipe 39 including a check valve l() leads `from the injector to the connection 86. A waste pipe il leads from the connection 87 and includes a valve rhe pipe 19 abovethe valve 25 and connection 26 is connected with the exhaust trom the hot water' heater (not shown). A conducting pipe 43 leads from the connection 26 to the tank il and includes a globe valve it near said tank; A discharge pipe i5 troni the fuel pump (not shown) is `connected' in the pipe i3 and a check valve 46 is included in the pipe A3 between the pipes 19'and A distribution pipe l? has one endI discharging into the tank l0' and includes a globe valve 48. A discharge pipe i9 includ: ing a globe valve 50 lea-ds from the connection of' the pipe to thefpipe iii'. The pipe entends to a waterv supply pipe 5l. including a globe valve 52. Above'the valve the pipe 5l has connection with the city watersupply.- A globe valve 53 is connected to the lower endot the pipe 5l and has a depending nozzle 54u connected therewith. A' water pumpen has a steainline 56 entering` its pump cylinder valve and an exhaust pipe 57 leading from said cylinder.

A hot water supply pipe 58 including a globe valve 59 is connected with thepunip. A 'l' GO is also included in the pipe 58. A branch or lateral pipe 6l extends 'lroin the T 60 to a T 62 in the pipe 51 between the valve 52 and the pipe 47. A pipe 63 connected with receiver and trap (not shown) Cil is connected in the pipe G1 at 64 and in chicles a globe valve 65 with a check valve (36 above. A. globe valve 67 is connected in the pipe G1 bet4 veen the connections 60 and G4. A. discharge pipe leads from the the pump to the boiler (not shown) and includes a globe valve The pipe G9 connects with a down pipe 70 which connects with the blow-etii pipe 71, which connects 'ith back or low end ot boiler. A city water service pipe 72 connects with the pipe 70 and includes a valve 73. A globe valve 74 is connected in the pipe 70 below the pipe .Above the pipe 72 a hot water pipe 75 is connected to the pipe 70 and includes a globe valve 76.

ln explaining the operation all valves are supposed to be closed and the tank 10 is .filled with one kind ot a treating compound and tank 11 may be filled with another kind or otherwise as is desired. A hose (not shown) may be attached to the nozzle 54. Cold water may be had at the nozzle by opening valves 52 and 53. It hot water is desired valve 67 is opened instead ot valve 52.

rlhe entire system is operated through the injectorI 15 and this is an important feature ot the invention as by its use cleaning coinpound may be circulated through any part of the plant and is not limited to the boiler alone.

It it is desired to remove incrustation the tank 10 is filled with a proper solution, such as caustic or alkaline solutions, well known in this art, and the valves 22, 17 and 34 are opened. The valve 17 supplies steam to injector from line 16 so that solution from the tank 10 is drawn up through pipe 19 into pipe 31 and passes upward through the Water column 33 to the boiler. The solution atter flowing through the boiler (not shown) is discharged when the blow-oil1 valve (not shown) of the boiler is opened, whereby all sediment and scale are blown out. This not only cleans the boiler but the water column as well.

lt it is desired to iill the tank 10, all valves beine` closed, the valves 48 and 52 are opened, thus cold water from the service pipe 51 will iiow through the pipe 47 to the tank. It hot water is desired the valve 52 is closed and the valve 67 is opened. It steam is desired, all valves being closed, valves 34 and 53 are opened so that steam will flow from the column 33 through the pipe 32 to the tank.

Should it be desired to pass solution through hot water heater, the pump 55 is stopped and all valves being closed, valve 67 is opened. 1Valves 17 22 and 50 are opened., whereby steam is supplied to the injector and the solution is drawn up through pipes 19 and 31 as before. For circulating the solution through the receiver and trap (not shown), valve is opened instead ot valve 67 and solution received from pipes 47 and 49, the operation being otherwise the same, except that compound solution will be discharged into boiler, thus cleaning all parts through which the solution passes.

1r' the pump 55 is to be cleaned, valves 17, 22, 50, G7 and 59 are opened whereby discharge from injector 15 will pass through pipes 39, 49, 47, 51, 61 and 58 to the pump. '.lhe compound solution will then be discharged through pipes 63 and by opening valves 69 and 74 the solution will be fed to the boiler through pipe 70.

City water service pipes 51 and 72 may be cleaned by cutting olli' the main service \f*al\f'e (not shown) and opening the valve 52, then opening valves 17, 22, 50, and 73, whereby the injector will torce the solution from pipe 47 through the pipes 51, 70 and 72. litter this is done injector is cut ol and valves 50 and 52 are closed, then main service valve is opened and the city water pipes are washed out.

For cleaning iloors and equipment a hose may be attached to the nozzle 54 and a soap and lye solution made up in the tank 10. nifhe injector 15 is started as before and the solution discharged through pipe 47, valve being opened, to the hose. For all cleaning purposes it will be noted that valves and 30 are opened for a supply ot liquid trom the tanks 10 and 11 by suction; while discharge or distribution is had by opening valves 34, 50, 38 and 48.

By means ol the auxiliary storage tank 11, the exhausts ot the solution from various elements are saved and may be reused. By reason of the check valve 46 iiuids trom the pipes 43 and 45 cannot pass into the pipe 19. All exhausts coming through pipe pass to the pipe and thence to tank 11. Then valve 25 is opened and valve 22 is closed suction from pipe 19 above valve 22 will communicate through pipe 31 to the injector; also when the injector is not operatingl and valve 25 is closed water may pass from the T 26 on pipe 19 past check valve 46 and through pipe 43 to the tank 11.

It it is desired to take a solution out ot the auxiliary tank 11, valve 30 is opened whereby solution is drawn up through pipes 27, 19 and 31 to the injector, the same being operated by opening valve 17. Then by opening valve 34 solution is conducted to the boiler through water column 33; or by closing valve 34 and opening valve 50 solution will be discharged into pipes 49 and 47. lt is obvious that by manipulating the dii-ferent valves various circulations ot the fluids may be had and it is not deemed neccessary to describe them all.
